🔌 Function

The ignition coil generates high-voltage spark for the spark plug so the cylinder can fire reliably during starting, idle and running load.

Common signs of failure:

• No spark

• Weak or intermittent spark

• Hard starting

• Rough idle

• Misfire under load

• Engine stalls or loses spark when warm

• Coil body cracked or plug lead damaged

• Spark returns when a known-good coil is fitted

📦 Condition

• Genuine used part

• Removed from running engine where applicable

• In good working condition unless otherwise stated
